The work was aimed to determine the level of oral dysbiosis of patients depending on the type of prosthetics constructures. MATERIALS AND METHODS: The study involved 48 patients with the presence in the oral cavity of fi xed dentures from 4 to 6 units with a service life of no more than 3 years. The samples of plaque from the vestibular surface of dentures were collected to determine the microorganisms in the gingival plaque. Bacteriological research was carried out by the multiplex polymerase chain reaction in real time using the Phemofl or 8 reagent kit. The degree of dysbiosis of the oral cavity was determined according to the classifi cation of V. Khazanova. RESULTS: The results of the study of patients' samples did not reveal signifi cant changes in the microbial landscape of the cervical areas. The total bacterial mass in the group of healthy individuals was lower than the total bacterial mass of patients in the investigated group signifi cantly. IV degree of oral dysbiosis with a decrease in the number of lactobacilli, streptococci was characteristic of patients of denture wearers. The II degree of dysbiosis in patients with metal-ceramic structures was established. Patients who used solid cast and metal-plastic structures were diagnosed with II-III degree of dysbiosis of the oral cavity. The worst indicators were characteristic of prosthesis wearers of stamped-brazed structures. CONCLUSIONS: Quantitative indicators of the composition of the microbiota of the cervical areas of denture wearers have signifi cant differences and different levels of dysbiosis of the oral cavity, depending on the type of dentures in the patients' mouth (Tab. 2, Fig. 1, Ref. 21).

Agricultural enterprises are active participants of the trade finance market. Purchasing plant protection products, they take out a loan or pay off using promissory note. Today the schemes of interaction between participants, the services cost and other parameters are not well studied. The aim of researchto construct patterns interaction of the entities and explore the cost efficiency of alternative trade finance transactions, using DCF methodology. The research explores the schemes of interaction between agricultural producer, distributor and guarantor bank with promissory notes and bills of exchange. It is justified that a promissory note provides an additional income, bill of exchange increases the number of customers by granting a deferment. The financial scheme for producers without direct banking borrowing is proposed. SantraukaŽemės ūkio įmonės aktyviai dalyvauja prekybos finansų rinkoje. Įsigydami augalų apsaugos produktus, jie pritraukia paskolą arba sumoka su vekseliais. Šiandien dalyvių sąveikos, paslaugų kainos ir kitų sandorio parametrų schemos nepakankamai ištirtos. Straipsnio tikslas -suformuluoti subjektų sąveikos modelį ir ištirti alternatyvaus sandorio skaičiavimo ekonominį efektyvumą, taikant teorinę, empirinę ir DCF metodiką. Straipsnyje nagrinėjami žemės ūkio gamintojų, platintojų ir garantų banko sąveikos modeliai, naudojant vekselius. Patvirtinta, kad vekselis suteikia papildomų pajamų, vekselis padidina klientų skaičių, suteikdamas atidėjimą. Siūloma finansinė schema gamintojams, neturintiems tiesioginio skolinimosi.Raktiniai žodžiai: žemės ūkio tiekimo grandinė, ekonominis efektyvumas, efektyvi palūkanų norma, garantija vekseliui, vekselis, prekybos finansavimas.JEL kodai: G21, G23, Q14.
